From the dot plot, we have that 90.91% of the students have 5 or more vowels in their first and last names.
---------------------
The dot plot states that:
- 2 students have 4 vowels in their first and last name.
- 3 students have 5 vowels.
- 8 students have 6 vowels.
- 9 students have 7 vowels.
Then:
- Total of 2 + 3 + 8 + 9 = 22 students.
- 3 + 8 + 9 = 20 have or more vowels.

90.91% of the students have 5 or more vowels in their first and last names.

<span>we have to solve simultaneous equations.
x = 10 oz. boxes
y = 16 oz. boxes
simultaneous equations
x + y = 24 ---1)
3.50x + 5.00y = 97.50 ----2)
to solve for x we need to eliminate y, therefore we have to multiply 1st equation by 5
5x + 5y = 120 --3)
subtract 3) - 2)
5x - 3.50x = 120 - 97.50
1.50x = 22.5 x = 15
number of 10 oz. boxes are 15. answer is d.15</span>
We are given with the expression y<span> = b cos t + t2 sin t and is asked to differentiate the function in terms of t. Based in the power law and law of products, we apply these to the given expresssion. the derivative is y' = -b sin t + t^2 * (cos t) + sin t * 2t. This is equal to </span>y' = sin t (-b +2t) + t^2 cos t.
